This abstract first appeared for US patent application 19009108 titled 'PHYSICAL RANDOM ACCESS CHANNEL ENHANCEMENT FOR INTER-CELL MULTIPLE TRANSMISSION AND RECEPTION POINT
Original Abstract Submitted
Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE) generally including receiving signaling indicating a set of physical random access channel (PRACH) configurations, receiving,, a physical downlink control channel (PDCCH) order to trigger a PRACH transmission associated with an additional PCI different from a first PCI associated with a serving cell, transmitting a PRACH associated with the additional PCI based on one PRACH configuration of the set of PRACH configurations that is associated with the additional PCI, receiving an indication of a timing advance (TA) associated with the additional PCI, and applying the TA for an uplink transmission associated with the additional PCI.
